Crimean Tatars - and, possibly, some others - are currently protesting in front of the Cabinet of Ministers' building - have been there since April, I was told:
I noticed them accidentally on May 12, but it was past 6 PM already, so they were done for the day:
Some of their slogans:
"Ukraine's Cabinet of Ministers is to blame for land conflicts in Crimea."
"Ukraine's Cabinet of Ministers is causing social tensions in Crimea."
"Ukraine's Cabinet of Ministers, start helping the peoples of Crimea already!"
"Yulia Vladimirovna, take the bureaucrats out of your ears - HEAR THE PEOPLE!!!" and "Yulia Vladimirovna, take the bureaucratic blinders off your eyes and see the problems of the people."
